Longitudinal relationship between quality of life and negative life events among adolescents during COVID-19 pandemic: a cross-lagged panel analysis

BACKGROUND

The negative association of quality of life (QoL) and negative life evens (NLEs) among adolescents has been proved by cross-sectional studies, without exploring sex differences. This study aimed to explore the longitudinal associations between QoL and NLEs among adolescents during novel coronavirus disease 2019 (COVID-19) pandemic and whether there are sex or age differences.

METHODS

A stratified cluster sampling was used to select 1421 students in primary school and middle school in Chongqing, China. From November 2020 (T0) to December 2021 (T2), the Adolescent Self-Rating Life Events Checklist and the Adolescent Quality of Life Scale were used to collect 3 waves of data. The correlations between study variables were conducted by the Pearson correlation analyses. The direction and strength of the longitudinal associations were analyzed using cross-lagged panel analyses.

RESULTS

Results showed significant changes in both variables during COVID-19 pandemic (P < 0.001). Cross-sectional analyses showed stable negative correlations between NLEs and QoL stratified by sex or by age (P < 0.001). Sex and age differences in longitudinal relationships were shown by cross-lagged panel analyses. For males, NLEs had a short-term bi-directional association with QoL [βA-D = -(0.091-0.340), P < 0.05]; for females, QoL had a short-term correlation with NLEs [βA = -0.119), βC = -0.109), P < 0.001]. In the youngest age group, NLEs had a short-term bi-directional correlation with QoL [βA-D = -(0.098-0.428), P < 0.05]. There was a short-term association between total QoL and NLEs among students except the 14∼15 year group [βA = -(0.071-0.149), βC = -(0.086-0.119), P < 0.05], the long-term association between total QoL and NLEs was only significant in adolescents aged 14∼15 years (βE = -0.132, P < 0.05). The strength of NLEs was slightly higher than that of total QoL, but lower than that of QoL in each dimension.

CONCLUSION

There were negative longitudinal relationships between NLEs and QoL during COVID-19 pandemic, and the strength of the associations varied across sex or age. Strengthening QoL in different dimensions may be a promising way to reduce NLEs during the pandemic among adolescents, and interventions should be tailored according different sex and ages.

Impact of respite care on health-related quality of life in children with medical complexity: A parent proxy evaluation

PURPOSE

This study examined the impact of respite care received by children with medical complexity (CMC) on their health-related quality of life (HRQOL). We hypothesized that out-of-home respite care would increase both opportunities to engage in activities and participation with non-family members and help with acquiring autonomy and social skills.

DESIGN AND METHODS

This cross-sectional study of CMC aged between 8 and 18 years living at home used a web-based questionnaire survey that parents living with the target CMC answered for proxy evaluation of CMC's HRQOL (KIDSCREEN-27). We asked 3142 parents to participate in the study through 237 special-needs schools throughout Japan. Path analysis was used to estimate the variation in each aspect of HRQOL with respite care time of in-home care services, day care services, short-stay services, and school time.

RESULTS

We analyzed the responses from 618 parents of CMC. The results showed that respite care by day care services and special-needs schools increased "physical well-being," "psychological well-being," and "peers and social support," which are components of the HRQOL. Furthermore, respite care at schools had an impact on "school environment."

CONCLUSIONS

Respite care provided by special-needs schools and day care services has implications not only in terms of relief for caregivers but also in improving the HRQOL of CMC.

PRACTICE IMPLICATIONS

Nurses can provide respite care that does not require parental accompaniment at school or day care facilities, which can lead to CMC's involvement in fostering autonomy and social skills. (249/250 words).

Validation of the Chinese Version of KIDSCREEN-10 Quality of Life Questionnaire: A Rasch Model Estimation

The KIDSCREEN-10 was deemed as a cross-national instrument for measuring Health-Related Quality of Life (HRQoL). However, no empirical endeavor has explored its reliability and validity in the context of China. This study aims to translate and validate the Chinese version of the KIDSCREEN-10 questionnaire. The KIDSCREEN-10 was translated into Chinese (Mandarin) using a blindly bilingual forward–backward–forward technique. A cross-sectional survey, including 1,830 students aged from 8 to 18 years, was conducted in a county located in Gansu province, China. Psychometric properties were evaluated using the Rasch partial credit model, ANOVA, and the correlation analysis. Results indicated that the KIDSCREEN-10 performed good internal consistency, known-group validity, and concurrent validity, but there were still some deficiencies in psychometrics: first, disordered response categories were found between category 2 (seldom) and category 3 (sometimes); second, item 3 (“Have you felt sad?”), item 4 (“Have you felt lonely?”), and item 5 (“Have enough time for self?”) demonstrated misfit to the Rasch model; third, items 3 and 4 exhibited differential item functioning. After collapsing the disordered response categories and removing the three misfit items, the seven-item questionnaire performed good psychometric properties. However, the seven-item version does not cover the psychological well-being dimension of HRQoL, and that may lead to inappropriate measures of HRQoL. Therefore, this paper suggested to use classical test theory to investigate the psychological properties of the KIDSCREEN-10.

Analysis of factors related to low health-related quality of life in children with epilepsy using a self-assessed Japanese version of the KIDSCREEN-52

BACKGROUND

There is a paucity of studies on self-assessed generic health-related quality of life (HRQOL) in children with epilepsy. The purpose of this study was to investigate generic HRQOL and associated factors among Japanese children with epilepsy.

METHODS

In this clinic-based study, 277 children (aged 8-18 years) with epilepsy and 429 children without any chronic illnesses were recruited. HRQOL was evaluated using the Japanese version of the KIDSCREEN-52 self-reported questionnaire, which consisted of 52 items categorized into 10 dimensions related to the environment surrounding children. Multiple regression analysis was applied to explore related factors with low HRQOL in each dimension.

RESULTS

We obtained the questionnaire from 171 (61.7%) and 306 (71.3%) children in the epilepsy and control groups, respectively. Short treatment period (<2 years), seizure lasting >30 min, and post-ictal symptoms were associated with a low HRQOL for School Environment (OR: 3.81; 95% CI: 1.34-10.86), Moods & Emotions (OR: 3.82; 95% CI: 1.67-8.78), and Parent Relations & Home Life (OR: 3.53; 95% CI: 1.29-9.72) dimensions, respectively. Complex neurodevelopmental disorders were associated with a low HRQOL for Social Support & Peers (OR: 3.59; 95% CI: 1.33-9.66), School Environment (OR: 2.49; 95% CI: 1.07-5.77), and Psychological Well-being (OR: 3.47; 95% CI: 1.20-10.00) dimensions.

CONCLUSIONS

Our results suggest that early psychosocial support and better management of epilepsy may improve HRQOL. More support in school environments may be required for children with epilepsy and neurodevelopmental disorders.

Assessment of self-/parent-reported quality of life in Japanese children with haemophilia using the Japanese version of KIDSCREEN-52

INTRODUCTION

Assessing health-related quality of life (HRQOL) is critical for providing comprehensive clinical care to patients with haemophilia. HRQOL in individuals with similar cultural backgrounds should be compared using internationally standardized, generic questionnaires.

AIM

To evaluate self-/parent-assessed HRQOL in Japanese children and adolescents with haemophilia A or B.

METHODS

Children and adolescents aged 8-18 years were enrolled. The haemophilia group comprised families with haemophilia, and the control group comprised those without chronic illness. HRQOL was assessed using the self-/parent-reported questionnaire KIDSCREEN-52, the Japanese version. The Oslo 3-Item Social Support Scale was investigated.

RESULTS

The questionnaire was completed by 36 families in the haemophilia group and 160 parents and children in the control group. Haemophilia children aged 8-12 years had lower scores for 'moods and emotions' than control children; the parents had lower scores in the haemophilia group than in the control group for 'moods and emotions', 'social support and peers', and 'school environment'. No significant differences in HRQOL were observed between both groups of adolescents aged 13-18 years or their parents. Neck-shoulder pain was associated with a low psychological state, including 'self-perception', but other joint pains did not affect the outcomes of the HRQOL indices. Social support weaknesses were associated with low physical and psychological states, whereas unexpected hospital visits identified low values for 'self-perception', 'autonomy', and 'school environment'.

CONCLUSION

Proactive mental and clinical care in haemophilia families, especially with young children, will foster a better environment for patients and their parents and ease concerns about progress in haemophilia.

Influence of Self-Esteem and Psychiatric Diagnosis on Health-Related Quality of Life in Children and Adolescents with School Refusal Behavior

BACKGROUND

School refusal behavior (SRB), which is the refusal to attend or remain in school, has been associated with emotional, psychological, and other behavioral problems, as well as a lower health-related quality of life (HRQOL). However, the effects of self-esteem and a psychiatric diagnosis in students with SRB on HRQOL are not yet known. Understanding these relationships could help to develop more effective therapeutic interventions.

METHODS

A total of 175 young people (aged 8-18 years old) who visited our medical centers and outpatient clinics participated in the study. This comprised the SRB group (n = 70) and an age- and sex-matched control group (n = 105). Information about any psychiatric diagnosis was collected from medical records, HRQOL was measured using the J-KIDSCREEN-52, SRB was assessed using the School Refusal Assessment Scale-Revised for Japanese Attendance at School, self-esteem was measured using the Rosenberg Self-Esteem Scale, children's mental health status was measured using the Strengths and Difficulties Questionnaire, and social support was measured using the Oslo 3-item Social Support Scale. We performed between-group comparisons and multiple regression analysis.

RESULTS

The SRB had a significantly lower HRQOL than the control group in several of the KIDSCREEN-52 dimensions. In the SRB group, 35.7% had chronic disease and 35.7% of their parents had health problems and were receiving treatment. The multiple regression analysis revealed that, within the SRB group, a psychiatric diagnosis was associated with a lower HRQOL. However, this was not the case for a diagnosis of autistic spectrum disorder. Self-esteem positively affected HRQOL in six dimensions of the KIDSCREEN-52 within the SRB group.

CONCLUSION

Our results could inform the development of support strategies for young people with SRB. Namely, support that enhances self-esteem could be used to increase HRQOL in young people with SRB. Furthermore, the presence of psychiatric disorders should be assessed as early as possible.

Psychometric properties of the Mandarin Chinese version of the KIDSCREEN-52 health-related quality of life questionnaire in adolescents: a cross-sectional study

PURPOSE

To evaluate the psychometric properties of the Mandarin Chinese version of KIDSCREEN-52 health-related quality of life (HRQOL) questionnaire.

METHODS

We conducted a cross-sectional study with two cohorts of school-based data in the urban areas of Weifang, China. 4385 and 841 representative adolescents aged 11-17 years have recruited into the baseline and test-retest group, respectively. Psychometric analyses included feasibility, item and dimension properties, reliability, construct validity, measurement invariance, convergent and discriminant validity, and known-group validity.

RESULTS

The response rates of both baseline and test-retest surveys were more than 90%. Low missing values were found (0.02-1.92%) across ten dimensions. The measurement properties of items were satisfactory. Noteworthy ceiling effects were observed for ten dimensions (6.75-31.84%), while the observed floor effects were negligible (0.02-1.37%). Internal consistency was robust with Cronbach's alpha (0.819-0.959), while the test-retest reliability was acceptable with the ICCs (0.724-0.849). Confirmatory factor analysis confirmed the ten-dimensional structure and supported the configural and metric invariance across gender and age groups. The Pearson correlation coefficients between the KIDSCREEN-52 and the PedsQL™ 4.0 were stronger in comparable dimensions than those in less comparable dimensions, demonstrating the convergent and discriminant validity. In most dimensions, statistically significant and medium or large effect size differences were found across socioeconomic and mental health status, supporting the known-group validity.

CONCLUSION

These findings demonstrate that the Mandarin Chinese version of KIDSCREEN-52 seems to work well in a Chinese context, and is a psychometrically valid and reliable HRQOL instrument.

Assessing health-related quality of life in Japanese children with a chronic condition: validation of the DISABKIDS chronic generic module

Background

This study examined the reliability and validity of the Japanese versions of the DISABKIDS-37 generic modules, a tool for assessing the health–related quality of life (HRQOL) of children and adolescents with a chronic condition.

Methods

The study was conducted using a sample of 123 children/adolescents with a chronic medical condition, aged 8–18 years, and their parents. Focus interviews were performed to ensure content validity after translation. The classical psychometric tests were used to assess reliability and scale intercorrelations. The factor structure was examined with confirmatory factor analysis (CFA). Convergent validity was assessed by the correlation between the total score and the sub-scales of DISABKIDS-37 as well as the total score of KIDSCREEN-10.

Results

Both the children/adolescent and parent versions of the score showed good to high internal consistency, and the test-retest reliability correlations were r = 0.91 or above. The CFA revealed that the modified models for all domains were better fit than the original 37 item scale model for both self-report and proxy-report. Moderate to high positive correlations were found for the associations within DISABKIDS-37 sub-scales and between the subscales and total score, except for the treatment sub-scale, which correlated weakly with the remaining sub-scales. The total score of the child-reported version of KIDSCREEN-10 correlated significantly and positively with the total score and all the sub-scales of the child-reported version of DISABKIDS-37 except the Treatment sub-scale in adolescents.

Conclusions

The modified models of Japanese version of DISABKIDS generic module were psychometrically robust enough to assess the HRQOL of children with a chronic condition.

Embodied conversational agents for multimodal automated social skills training in people with autism spectrum disorders

Social skills training, performed by human trainers, is a well-established method for obtaining appropriate skills in social interaction. Previous work automated the process of social skills training by developing a dialogue system that teaches social communication skills through interaction with a computer avatar. Even though previous work that simulated social skills training only considered acoustic and linguistic information, human social skills trainers take into account visual and other non-verbal features. In this paper, we create and evaluate a social skills training system that closes this gap by considering the audiovisual features of the smiling ratio and the head pose (yaw and pitch). In addition, the previous system was only tested with graduate students; in this paper, we applied our system to children or young adults with autism spectrum disorders. For our experimental evaluation, we recruited 18 members from the general population and 10 people with autism spectrum disorders and gave them our proposed multimodal system to use. An experienced human social skills trainer rated the social skills of the users. We evaluated the system’s effectiveness by comparing pre- and post-training scores and identified significant improvement in their social skills using our proposed multimodal system. Computer-based social skills training is useful for people who experience social difficulties. Such a system can be used by teachers, therapists, and social skills trainers for rehabilitation and the supplemental use of human-based training anywhere and anytime.

Reliability and validity of Japanese versions of KIDSCREEN-27 and KIDSCREEN-10 questionnaires

OBJECTIVE

This study aimed to assess the reliability and validity of Japanese versions of the KIDSCREEN-27 (J-KIDSCREEN-27) and KIDSCREEN-10 (J-KIDSCREEN-10) questionnaires, which are shorter versions of the KIDSCREEN-52 (J-KIDSCREEN-52).

METHODS

The present analyses are based on a pre-existing dataset of the J-KIDSCREEN-52 validation study, including 1564 children and adolescents aged 8-18 years and their 1326 parents. All were asked to complete the J-KIDSCREEN and Pediatric Quality of Life Inventory (PedsQL) questionnaires. Test-retest reliability was assessed with Intraclass Correlation Coefficients (ICCs) in a one-way random effects model, and internal consistency reliability was measured using Cronbach's alpha coefficients. Agreement between child and parent scores was evaluated using ICCs in a two-way mixed effects model. To assess concurrent validity, a sub-sample of 535 parents evaluated their child's mental health status using the Strengths and Difficulties Questionnaire (SDQ).

RESULTS

For children, test-retest ICCs were ≥0.60 and Cronbach's alpha ≥0.70 for every dimension of both instruments. Correlations of corresponding dimensions between the J-KIDSCREEN-27 or -10 and the PedsQL were acceptable. For parents, test-retest ICCs were ≥0.60, Cronbach's alpha ≥0.70, and ICCs between child and parent scores ≥0.41 in every dimension of both instruments. In multivariate logistic regression models, after adjusting for confounders, lower health-related QOL in every dimension of both instruments, except Physical Well-being, was significantly associated with higher odds ratios for borderline and clinical ranges of the SDQ.

CONCLUSION

The child/adolescent and parent/proxy versions of the J-KIDSCREEN-27 and J-KIDSCREEN-10 demonstrated acceptable levels of reliability and validity.
